PALE THRUSH. 197 
between male and female and different ages of young 
not known.—Temminck. 
Figured by Werner, in the “Atlas to the Manual,” 
‘under the name of Turdus Naumannii, and by Gould, 
Shor, i.” . 
In the next number I shall figure and describe 
T. cyaneus, but I take this opportunity of noticing 
several species, some of which have been included by 
Schlegel and others in the European fauna, and I will 
quote the remarks of Schlegel himself upon these birds 
in his “Revue” of 1844, as the best authority for 
omittmg them from this work. The question of 
determining with exactness the claims of admission into 
the European lists of many of these stragglers is very 
difficult, and I have already incurred the rebuke of 
the reviewer of my work in the “Ibis” on this point. 
Sins of omission are, however, equally great with those 
of commission, and I must content myself with the 
exercise of the best judgment I can give of the evi- 
dence on both sides, and perhaps by this means I shall 
at least avoid the error of being too confident upon a 
confessedly difficult question in ornithology. 
Turdus Barbaricus, Gmelin.—Frequents, according to 
Risso, the environs of Nice. I cannot give any account 
of this doubtful species, and therefore pass it in silence. 
Turdus rufus, Brisson.—Said by Schinz to have been 
observed in England, but as he has not indicated the 
source from whence he has derived this information, 
I have not adopted this species among those observed 
in Europe. 
Turdus Sibiricus, Pallas—Introduced into Temminck’s 
“Manual” among the birds of Europe, from one indi- 
VOL, I. 25
